Direct observation of band-gap closure for a semiconducting carbon nanotube in a large parallel magnetic field
arXiv:1011.3330 · doi:10.1103/PhysRevLett.106.096802
Abstract
We have investigated the magnetoconductance of semiconducting carbon nanotubes (CNTs) in pulsed, parallel magnetic fields up to 60 T, and report the direct observation of the predicted band-gap closure and the reopening of the gap under variation of the applied magnetic field. We also highlight the important influence of mechanical strain on the magnetoconductance of the CNTs.
